| A | B |
|---|
| intertidal zone | closest to shore, under water part of day and above water part of day |
| shallow-ocean zone | starts at low tide line and ends with sharp drop off, has the most ocean life |
| open-ocean zone | greatest depth, most difficult to study, missing nutrients and light, most difficult for ocean life to exist |
| live in open ocean zone | fish with bioluminescent bodies |
| food | high tide brings this to animals |
| during high tide | animals in intertidal zone are pounded by waves |
| light | this is needed by producers in the shallow ocean zone but not the deep ocean zone |
| camouflage | an adaptation that helps fish survive |
| water depth | is used to divide the ocean into its 3 major zones |
| spring tides | higher caused by gravity from the sun and moon pulling on the earth |
| neap tides | the lowest tides |
| currents | caused by water moving from the warm equator toward colder poles and land masses |
| water | 75% of the earth's surface is covered by this |
| rivers | carry salts and minerals as they empty into the ocean, this is what makes the ocean salty |
| plankton | start most ocean food chains |
| gulf stream current | this is the ocean current which affects our weather the most |
